Locating structure of a water control valve

Abstract

The present invention provides an improved locating structure of a water control valve casing. There are first and second coupling portions opposite to each other on the casing and base, as well as a locator for combining the first and second coupling portions. The first and second coupling portions are either punch holes or guide channels opposite to the snapping channel, which are separately screwed or snapped by a pin column or C-shaped locator. The locator permits positioning by screwing with the pin column, or by snapping with a C-shaped fastener. The casing and base of the water control valve are engaged more securely, thus protecting the internal components with improved applicability.

1 . A locating structure of a water control valve casing, said casing being a hollow housing defining a wall and internal space and having a base assembled onto bottom thereof and a perforating hole, said casing and base being positioned securely, said locating structure comprising:
 a first and second coupling portion opposite each other on said casing and base; and   at least a locator, combining said first and second coupling portion.   
   
   
       2 . The locating structure defined in  claim 1 , wherein said first coupling portion is a punch hole on said wall of said casing, said second coupling portion being a convex seat with a punch hole on said base, said locator being a pin column, said pin column screwing into the punch holes of the wall of the casing and convex seat. 
   
   
       3 . The locating structure defined in  claim 1 , wherein said first coupling portion is a lateral bulge with a punch hole on said wall of said casing, said second coupling portion being a lateral convex seat with a punch hole on said base, said locator is a pin column, said pin column screwing into the punch holes of a lateral bulge and lateral convex seat. 
   
   
       4 . The locating defined in  claim 1 , wherein said first coupling portion is a convex guide seat with two guide channels on said wall of said casing, said second coupling portion being a convex clamping frame with two snapping channels on said base, said locator being a C-shaped fastener and snapping into a guide channel of said convex guide seat and snapping channel of convex clamping frame.
